	@davidalgarve The dongle I bought allows the standard Mitsu adapter to plug into it so you can have both. Ive copied in the chap I bought it off so hopefully he will be able to answer the technical qu...
	RE: Melpump Users Anywhere? By DavidAlgarve, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Very interesting and I wonder how it compares with Havenwise? I see that it connects through CN105 and that is the connector that my WiFi link to MelCloud is connected to. Do you somehow retain a lin...
	RE: One room is colder than the rest of the house By Pie_Eater, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Thanks both. i hadnt really considered the heat loss reducing on the 1st floor. that makes sense. Yes we pushed back on all radiators - the ones they wanted to install were ugly an we suspected most ...

	@agentgeorge High Voltage means different things in different circumstances; as an audio engineer, I used 48 v. DC to power microphones and this is known as ‘Phantom Powering’ but does not require hig...
	Melpump Users Anywhere? By bontwoody, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Ive just installed a dongle that allows me to monitor and communicate with an Ecodan through Melpump. Its a snip at £35 but there isnt a lot of documentation I can find. Does anyone on here use it? H...

	RE: Battery disconnected By Eliuccio, 2 weeks ago Forum Energy Storage
	I am pretty sure he assessed both. What I can report is that I emailed Cahill and Growatt asking them to pay a visit and assess the battery (on warranty). No reply as yet. Thanks everyone for the in...
	RE: Battery disconnected By Transparent, 2 weeks ago Forum Energy Storage
	Indeed, on p.19 Attachment : image.png That's the same page I was referring to earlier, where the connection of the power cables suggests that the battery packs are being connected in parallel....
	RE: New build installation query By JamesPa, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
	Agree with the above. What diagrams/instructions do you have, what model of heat pump, some photos including photos of the controller settings. In general please do expect a heat pump to be on 24x7 w...
	RE: One room is colder than the rest of the house By AndrewJ, 2 weeks ago Forum Air Source Heat Pumps (ASHPs)
